Bantu trims.​

Penjelasan:

Diket :

Vp = 120 Volt

Vs = 9 Volt

Ns = 30 lilitan

Is = 400 mA

Ditanya :

a) Np

b) Ip

c) P

Jawab :

a) Np = Ns x Vp/Vs

Np = 30 x 120/9

Np = 3.600/9

Np = 400 lilitan

b) Ip = Vs x Is/Vp

Ip = 9 x 400/120

Ip = 3.600/120

Ip = 30 mA

c) P = V x I

P = 120 x 30

P = 3.600 watt
